9212311 ÷ 427 
Our goal is to divide 9212311 by 427.

Step 1:
When dividing 9 by 427, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 427

Moving on to step 2:
When dividing 92 by 427, we get 0 with a remainder of 92.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 92 after subtracting 0 from 92.
Take the next digit (1) from the dividend and append it to 92, then repeat: 921 / 427

Step 3:
921 divided by 427 is 2 with a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 854 away from 921, we end up with 67.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 427

Step 4:
When dividing 672 by 427, we get 1 with a remainder of 245.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 427 from 672, we get 245.
Fetch the next digit (3) from the dividend, attach it to 245 and continue: 2453 / 427

On to step 5:
The number 427 fits into 2453 5 times, leaving a remainder of 318.
Write down 5 as next digit of the result. 
Result so far: 215.0
Subtract 2135 from 2453 to get 318.
Fetch the next digit (1) from the dividend, attach it to 318 and continue: 3181 / 427

Let's proceed to step 6:
427 can be fit into 3181 7 times, resulting in a remainder of 192.
The next digit of our result is 7. 
Result so far: 2157.0
If we subtract 2989 from 3181, we get 192.
Take the next digit (1) from the dividend and append it to 192, then repeat: 1921 / 427

On to step 7:
427 goes into 1921 4 times with a remainder of 213.
Put 4 as the next digit of the answer. 
Result so far: 21574.0
If we take 1708 away from 1921, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 8:
427 can be fit into 2130 4 times, resulting in a remainder of 422.
Record the quotient 4 as the next digit in the result. 
Result so far: 21574.4
If we take 1708 away from 2130, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 9:
427 goes into 4220 9 times with a remainder of 377.
Put 9 as the next digit of the answer. 
Result so far: 21574.49
If we subtract 3843 from 4220, we get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 10:
3770 divided by 427 is 8 with a remainder of 354.
Record the quotient 8 as the next digit in the result. 
Result so far: 21574.498
The remainder is 354 after subtracting 3416 from 3770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 11:
427 can be fit into 3540 8 times, resulting in a remainder of 124.
Record the quotient 8 as the next digit in the result. 
Result so far: 21574.4988
Subtract 3416 from 3540 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The quotient of the division is 21574.4988, and the remainder is 0.00124.
